Energy-saving Modular Compact Fluorescent Lamp With A Detachable Glass Bulb Unit

Abstract

A modular compact fluorescent lamp integrated with automated on/off control that is comprised of two modules. The glass bulb unit (daughter unit) is separated from the main body and can be exchanged and refilled at a lower cost. The main body unit (mother unit) contains the most electrical circuitry control, extends the reliability of the product by reducing heat-generating components, and is designed to accommodate various colors and applications of the daughter unit without increasing the size of the compact fluorescent lamp.

1 . A fluorescent lamp comprising first and second subassemblies, said first subassembly comprising a sealed glass tube including a gas therein, said tube being adapted for electrical and mechanical connection to said second subassembly, said second subassembly including circuitry to activate said gas when said first and second subassemblies are connected, said second subassembly including an on/off control responsive to ambient light in excess of a present threshold level greater than that provided by ambient sunlight.  
   
   
       2 . A lamp as in  claim 1  wherein said first subassembly includes plug in connectors and a glow start.  
   
   
       3 . A lamp as in  claim 1  wherein said second subassembly includes filament heating components and is configured for connection to an incandescent bulb receptor.  
   
   
       4 . A lamp as in  claim 2  where in said second subassembly is adapted to mate with said plug connector.  
   
   
       5 . A sealed fluorescent tube said to be including therein a glow starter.  
   
   
       6 . A tube as in  claim 5  having first and second ends, each of said first and second ends having electrical connections for communicating with an external power source.  
   
   
       7 . Docking apparatus for communicating with the tube of  claim 6 , said apparatus including high frequency ballast for activating said glow starter, said apparatus being configured for mating with an incandescent bulb receptor.
